java.lang.NoClassDefFoundError: com.parse.Parse$Co

I am using parse.com sdk in my app. It is working absolutely fine with Lollipop. But when I run the app on below lollipop versions I get this error:

I'm getting this error when initialising parse by

Parse.initialize(this);

Application class code:

public class MyApp extends Application {
@Override
public void onCreate() {
    super.onCreate();
    // Enable Local Datastore.
    Parse.enableLocalDatastore(this);
    Parse.initialize(this);
}

}

My manifest code:

How can I fix this?

Looking at your dependencies and since you have confirmed you have multidex enabled, please consider this (quoting from the official documentation):

Versions of the platform prior to Android 5.0 use the Dalvik runtime for executing app code. By default, Dalvik limits apps to a single classes.dex bytecode file per APK. In order to get around this limitation, you can use the multidex support library.

It means you have to set the multidex support library in order to enable multidex and to be able to run your application on devices running a version of Android prior to 5.0.

The official documentation is quite straightforward and it's really simple to follow.

You basically have to:

enable multidex support in your defaultConfig section adding: multiDexEnabled true
declare the library as a dependency:

compile 'com.android.support:multidex:1.0.0'
skip the step where you have to set MultiDexApplication in the manifest as the application name (because you have your own Application class).

Since you have a custom Application class, please be careful while you set the multidex support library:
